    摘要： Low cost methods for fabricating microneedles are disclosed. According to one embodiment, the fabrication method includes the steps of: providing a substrate; forming a metal-containing seed layer on the top surface of the substrate; forming a nonconductive pattern on a portion of the seed layer; plating a first metal on the seed layer and over the edge of the nonconductive pattern to create a micromold with an opening that exposes a portion of the nonconductive pattern; plating a second metal onto the micromold to form a microneedle in the opening; separating the micromold with the microneedle formed therein from the seed layer and the nonconductive pattern; and selectively etching the micromold so as to release the microneedle. In another embodiment, the micromold is not required. The method according to this embodiment includes: forming a recess with an apex in a substrate; forming a seed layer on the substrate; forming a nonconductive pattern on a portion of the seed layer that is on a sidewall surface of the recess; plating an electrically conductive material over the seed layer and over the edge of the nonconductive pattern to form a plated layer with an opening that exposes a portion of the nonconductive pattern; and separating the plated layer from the seed layer and the nonconductive pattern to release a hollow microneedle with an offset opening.

    摘要： Various embodiments of the present invention are directed to methods for manufacturing complex, anisotropic materials with desirable properties for information storage, processing, and display. Certain of these methods involve employing a magnetic field during manufacture to induce desired orientations of precursors, subunits, and/or molecular subassemblies. The applied magnetic field steers the precursors, subunits, and/or molecular subassemblies into desirable orientations while the precursors, subunits, and/or molecular subassemblies are assembled or self-assemble into a complex, anisotropic material. One embodiment of the present invention is a class of new, complex, well-ordered, network-like materials that include a ferromagnetic-material-based framework in which organic and/or organometallic compounds are organized. The ferromagnetic-molecule-based framework provides a scaffold for assembling the stable, precisely separated layers of organic and/or organometallic compounds and maintaining the layers of organic and/or organometallic compounds in well-ordered, anisotropic arrangements. Additional embodiments of the present invention are directed to methods for manufacturing the new ferromagnetic-molecule-based, network-like materials.

    摘要： A method is provided for fabricating molecular electronic devices comprising at least a bottom electrode and a molecular switch film on the bottom electrode. The method includes forming the bottom electrode by a process including: cleaning portions of the substrate where the bottom electrode is to be deposited; pre-sputtering the portions; depositing a conductive layer on at least the portions; and cleaning the top surface of the conductive layer. Advantageously, the conductive electrode properties include: low or controlled oxide formation (or possibly passivated), high melting point, high bulk modulus, and low diffusion. Smooth deposited film surfaces are compatible with Langmuir-Blodgett molecular film deposition. Tailored surfaces are further useful for SAM deposition. The metallic nature gives high conductivity connection to molecules. Barrier layers may be added to the device stack, i.e., Al2O3 over the conductive layer.

    摘要： An apparatus for transverse characterization of materials includes a lower pattern of contacts, separated by spacings, a material, and an upper pattern of a multiplicity of contacts, separated by spacings differing from the spacings of the lower pattern. The transverse characterization method includes receiving lower pattern of a multiplicity of contacts, separated by spacings along a surface, with a material above the surface, successively placing an upper contact near the upper surface of the material in an upper pattern of locations separated by spacings differing from the spacings of the lower pattern, measuring the characteristics between the upper contact and one or more contacts of the lower pattern and evaluating the measured characteristics to previous measurements, wherein the evaluation provides the transverse characterization.

    摘要： A batch fabrication technique is described that increases the manufacturing efficiency of servo write heads and also improves servo pattern definition for fine features, while reducing tape and head wear. Multiple heads are fabricated as a batch from one or more ferrite wafers. A nominally flat, large wafer surface and a contour suitable for uniform photoresist application and planar photolithography permit fine servo pattern definition. A rounded leading edge on the head creates an air bearing to reduce wear of the tape and of the head. Moreover, any head wear occurs at the leading edge rather than in the region of the head where the servo pattern is formed. The servo write head may have a substantially planar head surface. A leading edge is disposed adjacent to the head surface such that the tape contacts the leading edge before passing over the head surface. The leading edge is rounded to form an air bearing between the head surface and the tape. A rounded trailing edge may be disposed adjacent to the head surface such that the tape passes over the trailing edge after passing over the head surface. The head may be formed from an upper ferrite wafer having a non-magnetic spacer. Non-magnetic material is photolithographically defined to produce gaps above the spacer. The non-magnetic material may be photoresist, semiconductor materials, glass, metal or the like. The material may even be removed later to leave air gaps. The non-magnetic material forms a region where the field loops out to intersect the passing tape, thereby transferring a magnetic pattern to tape. Additionally, a lower ferrite wafer may be mated to the upper ferrite wafer to complete a magnetic circuit around the gaps. The upper or lower ferrite wafer may have a channel through which an inductive winding passes. Multiple heads may be formed through batch processing of the upper and lower ferrite wafers.
